NUTRITIONAL FOUNDATION - Four scoops of Mass XXX provide over 780 calories when mixed with water, fueling energy utilization during training and replenishing glycogen stores post-exercise. - 127g of carbohydrates help prevent the body from using protein as energy, ensuring the 50g of fast, medium, and slow-digesting protein per serving can provide fuel for working muscle, recovery, and maximum gains^*.

POWER PLUS BLEND - BETAPOWER, a patented betaine anhydrous, is clinically dosed to support power and enhance athletic performance. - Creatine monohydrate and micronized creatine monohydrate work together to fuel high-intensity exercise and support muscle protein synthesis. - An herbal blend of Sphaeranthus indicus Flower Head Extract and Mangifera indica Bark Extract, clinically proven as MyoTOR, can improve muscle strength with half the exercise in as early as 2 weeks^*. - A blend of L-Arginine, L-Glycine, and Micronized L-Methionine serves as creatine precursors.

MICRONIZED AMINO ACIDS - Micronized L-Glutamine, one of the most abundant amino acids in muscles, is involved in protein synthesis and can help replenish muscle glutamine stores depleted by intense exercise. - Micronized L-Arginine is a precursor for synthesizing nitric oxide, proteins, and creatine - key components for fueling performance and gaining mass^. - Micronized L-Leucine, an essential amino acid, is crucial for regulating muscle protein synthesis, fueling muscle cells, and supporting protein balance^*.

IMMEDIATELY Mass XXX is a satisfying shake available in 4 delicious flavors, providing nutritional support to help you meet your macro goals with 50g of high-quality protein, 780+ nutrient-dense calories, up to 130g of carbohydrates, and healthy fats to support your mass gaining and performance goals^*.

2-6 WEEKS With the clinically proven MyoTOR, you can expect to see rapid performance results in as early as 2 weeks^. Coupled with a high-calorie diet, appropriate strength training program, and 1-2 servings of Mass XXX^ per day, you'll start to see weight gain and muscle growth to the MaXXX^. The Power Plus Blend and Micronized Amino Acids will provide beneficial muscle fuel for exercise during intense training, allowing you to experience max performance with 40% fewer sets^. You'll also notice improvements in muscle recovery when taken post-workout.

3-4 MONTHS & BEYOND Consistency (and training) has paid off, and you're feeling bigger, stronger, and fitter, ready to take on your next fitness challenge!
